Description
Network Management Systems
The CISCO2921-HSEC+/K9 Cisco 2921 Integrated Service Router has a number of network management systems that can be used to monitor, configure, and troubleshoot the router. Some of its key network management features include:
- Cisco IOS Software: The router runs on Cisco IOS Software, which is a feature-rich operating system that provides a wide range of management and configuration options. This includes command-line interface (CLI) and web-based graphical user interface (GUI) for configuration, monitoring, and troubleshooting.
- SNMP: The router supports Simple Network Management Protocol (SNMP), which allows for the monitoring and management of the router using a network management system (NMS). SNMP can be used to gather information about the router’s performance and to receive notifications of any issues that arise.
- NetFlow: The router supports NetFlow, a Cisco proprietary protocol, which allows for the collection and analysis of network traffic data. This can be used to identify trends and patterns in network usage, troubleshoot performance issues, and detect security threats.
- Cisco Prime: Cisco Prime is a network management software that allows for the central management of multiple Cisco devices, including the CISCO2921-HSEC+/K9 router. It provides a comprehensive view of the network, including real-time performance data, inventory, and configuration management.
- Cisco DNA Center: Cisco DNA Center is a network management software that provides a centralized view of the network and allows for automated provisioning and management of Cisco devices, including the CISCO2921-HSEC+/K9 router. It also provides analytics, automation, and assurance capabilities.
These management systems enable organizations to monitor and manage their network effectively, and ensure the smooth operation of the CISCO2921-HSEC+/K9 Cisco 2921 Integrated Service Router.
Routing Protocols and Configuration
The CISCO2921-HSEC+/K9 Cisco 2921 Integrated Service Router supports a variety of routing protocols, which can be used to configure the routing behavior of the router. Some of the key routing protocols and configuration options include:
- Interior Gateway Protocols (IGP): The router supports Interior Gateway Protocols (IGPs) such as Routing Information Protocol (RIP), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP). These protocols are used to exchange routing information between routers within an autonomous system (AS) and to determine the best path to a destination network.
- Border Gateway Protocol (BGP): The router supports Border Gateway Protocol (BGP), which is used to exchange routing information between routers in different autonomous systems. BGP is commonly used in service provider networks to connect to other service providers and to the Internet.
- Policy-Based Routing (PBR): The router supports Policy-Based Routing (PBR), which allows for the creation of routing policies that determine how packets are forwarded based on specific criteria, such as source IP address or destination port number. PBR can be used to override the default routing behavior of the router and to direct traffic to specific paths.
- Quality of Service (QoS): The router supports Quality of Service (QoS), which allows for the prioritization of different types of traffic. QoS can be configured to prioritize certain types of traffic, such as voice or video, over other types of traffic, such as data.
- Virtual Routing and Forwarding (VRF): The router supports Virtual Routing and Forwarding (VRF), which allows for the creation of multiple virtual routing tables on the same router. This can be used to segment a network into multiple virtual networks, each with its own routing table.
These routing protocols and configuration options provide a high degree of flexibility and allow the CISCO2921-HSEC+/K9 Cisco 2921 Integrated Service Router to be configured to suit the specific needs of an organization’s network.
Quality of Service (QoS) Capabilities
The CISCO2921-HSEC+/K9 Cisco 2921 Integrated Service Router supports Quality of Service (QoS) which allows for the prioritization of different types of traffic to ensure that critical applications, such as voice and video, receive the necessary bandwidth. Some of the key QoS capabilities of this router include:
- Class-Based Weighted Fair Queuing (CBWFQ): CBWFQ allows for the configuration of different traffic classes and assigns a specific amount of bandwidth to each class. This ensures that each class of traffic is allocated the appropriate amount of bandwidth and prevents one class of traffic from consuming all available bandwidth.
- Low Latency Queuing (LLQ): LLQ is a type of CBWFQ that prioritizes delay-sensitive traffic, such as voice and video, over other types of traffic. This ensures that delay-sensitive traffic is delivered with minimal delay and jitter.
- Weighted Random Early Detection (WRED): WRED is a congestion avoidance technique that drops packets when the queue is full, but it gives priority to certain types of traffic. This ensures that delay-sensitive traffic is less likely to be dropped during periods of congestion.
- Traffic Shaping and Policing: The router supports traffic shaping and policing, which allows for the rate-limiting of traffic to a specific value. This can be used to prevent a single host or application from consuming all available bandwidth.
- MPLS QoS: The router also supports Multi-Protocol Label Switching (MPLS) Quality of Service (QoS) which allows for the prioritization of MPLS traffic over non-MPLS traffic.
These QoS capabilities of CISCO2921-HSEC+/K9 Cisco 2921 Integrated Service Router allows for the effective management of network bandwidth and ensures that delay-sensitive traffic is delivered with minimal delay and jitter, which is essential for the smooth operation of critical applications such as voice and video.
